Fig. 147.—Full-size Pattern for the Boy Riders.

For the Platform shown directly under the horses and sleighs in [Fig. 135], cut a piece of cardboard 11 inches in diameter; if you choose to make the Ferris wheel before the merry-go-round, you may use the center pieces removed in cutting out the rims, as noted in [Fig. 153]. Punch a hole through the center of this disk large enough for the peg connecting spools D and E to slip through. This platform rests upon the top of spool D and revolves with it.

To Operate the Merry-go-round. The key by which the mainspring is wound up is shown screwed in place on the under side of the cigar-box cover in [Fig. 139]. While winding the mainspring, it will be necessary to have some means of checking it so it will not unwind at the same time, and the best scheme for a check is to bore a small gimlet hole through the cover of the cigar box and stick a match through this and run it between the spokes of one of the clock wheels so as to prevent it from turning. Then when you have wound up the spring and are ready to start the merry-go-round, all you have to do is to pull out the match.

The model of this toy which the author has before him runs for five minutes with one winding, and any boy can make one which will run as well if he follows the directions given and uses a reasonable amount of carefulness in the work.

Other Animals than horses may be used if you wish to follow the arrangement of some of the latest merry-go-rounds, and pictures of these may be found among the colored cut-outs sold in the stationery stores, or if you can draw well, you may copy them from books and magazines. Great fun may be had by changing the positions of the boy riders, making them ride backward part of the time and sometimes two and three boys on a horse.

Doubtless you have heard of the famous Ferris wheel, and a good many of you have ridden in the smaller wheels patterned after it, at the amusement parks, so you will be interested in making

A Miniature Ferris Wheel like the one shown in [Fig. 137].

The Standard for supporting the wheel ([Fig. 149]) consists of two triangular supports, one with a spool hub fastened to its top for the axle of the wheel to run through and the other with the cigar box inclosing the clockwork fastened to it. [Figures 150], [151], and [152] show the construction of these supports. Cut strips P and Q 12 inches long and R 10 inches long, and trim off the upper ends of P and Q so when they are nailed together the lower ends will be 8 inches apart; nail strip R to the lower ends of P and Q ([Fig. 150]). To fasten the spool hub to its support, smear one side of a piece of tape with glue and wind it several times around the spool ([Fig. 151]), then set the spool on top of the support and press the ends of the tape against the sides of strips P and Q ([Fig. 152]).
